no encoder so iv setup counter to handel the count and CW or CCW direction deciding theres just a single count in. ill change my links around and give it a shot cant see why it shouldt work now > On my HNC lathe, I have a tool turret, so I didn't use prepare-prepared: > ... > ### TURRET ### > # create signals for tool loading loopback > linkpp iocontrol.0.tool-prepare iocontrol.0.tool-prepared > linkpp iocontrol.0.tool-change turret.0.position-change > linkpp turret.0.position-changed iocontrol.0.tool-changed > ... > ( http://www.wallacecompany.com/cnc_lathe/HNC/emc2/configs/hnc_io-3a.hal ) > > My turret HAL component handles the turret control. > > I have a carousel on my Shizuoka, which I haven't gotten working yet: > http://www.wallacecompany.com/machine_shop/Shizuoka/tool_changer_video.html > http://www.wallacecompany.com/machine_shop/Shizuoka/00030-1a.jpg > > The plan is to have an twenty-four position encoder.
